Abstract

In this work, a novel phosphorus functionalized carbon nitride (PCN) was designed and synthesized by a pyrolysis method for rapid adsorption of uranium. The optimized sample obtained at 600 °C (marked as PCN-600) exhibited the highest ability for uranium adsorption with efficiency of over 96% in only 1 min. The PCN-600 also exhibited high selectivity for uranium adsorption from simulated wastewater containing multiple interfering ions. The characterization results further revealed that the main adsorption mechanism of the uranium on PCN-600 is chemisorption. This work provides newly insight into adsorbent design for uranium removal from wastewater.

磷功能化氮化碳对水溶液中铀的快速吸附

本文设计并合成了一种新型磷功能化氮化碳（PCN），用于铀的快速吸附。在600℃条件下获得的优化样品（标记为PCN-600）在1 min内表现出最高的铀吸附能力，吸附效率超过96%。PCN-600对含有多种干扰离子的模拟废水中的铀也表现出高选择性吸附。表征结果进一步揭示了铀在PCN-600上的主要吸附机理是化学吸附。这项工作为废水中铀的吸附剂设计提供了新的见解。
